The 1.8 installer does not. In 1.8, ECC requires TR1 which is not
available by default in VC. However in versions after 1.9.4 this
dependency was removed. I have not built new binaries for recent
1.9 releases, but an installer for 1.9.8 is available here:
That installer should provide full ECC support.

You'll probably want python at least. In theory you could set up
the build without it by replicating the actions configure.py
would take, but this would be very (_very_) tedious. There are
Win32 installers for Python available, for instance:
(make sure you install Python 2.x rather than the intentionally
incompatible Python 3.x)
You can also compile botan 1.8 with ECC using Visual Studio if
you install a TR1 implementation. For instance the TR1
implementation included in Boost works fine (just pass
--with-tr1-implementation=boost as an argument to configure.py).
